To all whom 'it mafy concern:

Be it lcnovv'nv that I, AARON L. Veo a. citizen of the' United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in InvertedGas-Burners, of which the following, when taken in connection with thedrawing accompanymg and formi u part hereof, is u full and completedescrlption, sulicient to enable those skilled iu the ort to understand,make, and use the same.

This invention relates to inverted gas burners provided with u Bunsenburner und a mantle; and the object ofthe invention is to obtain aburner by means of which, when the same has burned until the supplypipe, adjacent to the mantle, is heated, suiiicient gas will be suppliedand with suicient force to induce c suicient supply of nir so that nosmoke will be produced or emitted by the burner and a blue llame, as itis called, will continuously be produced.

A further object of the invention is to obtain u burner of the kindnamed which may be easily attached to an ordinary gas pipe, in lace ofthe ordinary tip or in place of an ordinary W'ellsbach burner, by onenot particularly skilled in the art, and properly ad- 'nsted to burn asdesired and to produce a lue flame.

In the drawing referred to as forming a part of this specificationFigure 1 is a side elevation of un inverted burner embodying thisinvention, showing a mantle thereon in suitable position for use. Fi 2is a side elevation, on an enlarged sca e. of the end of the pipe towhich an inverted burner embody' this invention may be attached. Fig. 31s a vertical sectional view of the Bunsen burner formi a part of thisinvention. Fig. 4 is o verticsectional view, on an enlarged-sle, of theupper end of the Bunsen burner fornuis-:g a part of this invention, andof the parts a )scent thereto, with the lower end of the onse neck ofthe burner. Fig. 5 is a vertica sectional view of a diminishing thimblefox-min an element in the device embodying this invention. F' 6 is avertical sectional view of a modi cation of the diminishing or thimbleof the device. F' 7 is an elevation of the base of the needle va neforming an element in the gas burner embed this invention, and F' 8 is atop plan view of the base of the nee le valve'.

.A reference letter applied to des ate a glven art is used to indicatesuc part thro out the several figures of the drawing, w crever the sameappears.

A is an ordinaryl ell.

AB is a Bunsen tube. Tube B is provided with the base C' and with airregulating sleeve E.

F is a. perforated tube.

G is an adjustable diminishing tube (see Figs. 2 and 3).

The air apertures in tube F are lettered j, f. Base C consists of theknurled part C provided with screw threads therein [itt-i fr over theordinary screw threads of gas e l A, the screw threaded parts C and Caand the needie C. there are provided the holes Cs thro h which gas mayflow to around the needle and underneath the cap D. Cap D is providedwith internal screw threads fitti over the screw threads C of base C, awith an aperture fitting over C of base C so that by turning such ca theaperture is more or less closed vb n le C. The foregoing described n evalve and base obtained by base C and cap D is the ordinaryconstruction.

K is the goose neck of the inverted burner and L is the mantle thereof.In the device embodying this invention the goose neck K is attached tothe Bunsen burner B by means of the interposed support M.

Su port M pre erably com rises the enlarg part m of the end of t e neckK, and the tube m' provided with the enlarged part m2 enga with enlargedpart m of goose neck K, an provided with the enlarged part m forminawind guard to air apertures f, f, in tube m* 1s a. groove m the upperend of tube m' to prevent such tube from falling down on tube E.

It will be observed that diminish G is of less area at the up er and d'end thereof (lettered g) an is the area of the passage through the gooseneck K (shown in the l:part of such goose neck adjacent to the e urgedpart m, in Fig. 4

Having thus described my invention what I claim as new and desire. tosecure by Letters Patient is;-

In u gas burner, the combination of a ges nozzle, a. tube secured boseid nozzle and having air admission openings ndjiwent;

thereto, n. longitudinali movable mixing cup frictionally held wit 1inthe tube and arranged to vary the size of the air admission opening,said cup having an exit of less aree than its entrance.
